Compile the Android 4.4.2 source code In the previous article, I shared with you the process of downloading the android 4.4.2 source code in the sky (see the whole process of downloading the android4.4.2 source code (with the downloaded source code). Now I will write down the compilation notes. Installing the JDK The master branch of Android in the Android Open Source Project (AOSP) requires Java 7. On Ubuntu, use OpenJDK. Java 7: For the latest version of Android $ sudo apt-get update$ sudo

Practical Android skills: Switch JDK under Ubuntu After Android L, we recommend that you use JDK 7 to compile the program. This is a natural development rule, just like compiling Android 1.6 4 years ago and using JDK 5. Multi-version JDK can coexist. You only need to use the update-alternatives tool to switch between them at any time. The following describes how to install openjdk and oracle jdk (cannot cope with sun) and switch the version.1.
